Ear question

I was looking at some photo's of Pit Bulls that are show dogs.....and they all have short pointy ears.
I thought this was natural, but when I saw their puppie pictures, they all had soft floppy ears???

Tail docking and ear cropping, unfortunately still common, has become more controversial in recent years. In 2008, the American Veterinary Medical Association passed a resolution opposing ear cropping and tail docking of dogs solely for cosmetic purposes, and encourage the elimination of ear cropping and tail docking from breed standards.

Since 2009, Banfield, The Pet Hospital, the nation's largest animal hospital network (with 800 hospitals and more than 2,000 vets nationwide), no longer performs tail docking, ear cropping or devocalization on dogs.
